The goal of this interventional clinical trial is to learn about TNG260, a CoREST inhibitor, in combination with pembrolizumab in patients with advanced solid tumors with a known STK11 mutation.

The main question[s] it aims to answer are:

  • the recommended dose for Phase 2
  • to evaluate the safety and tolerability of the combination therapy
  • to determine the pharmacokinetics of TNG260
  • to evaluate the initial antineoplastic activity

Participants will receive study treatment until they experience an undesirable side effect, their disease progresses or until they withdraw consent.

Official Title

A Phase 1/2, Open-Label Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Efficacy of TNG260 as Single Agent and in Combination With an Anti-PD-1 Antibody In Patients With STK11 Mutated Advanced Solid Tumors


This is a first-in-human Phase 1/2, open-label, multicenter, dose-escalation and expansion study designed to determine the maximum tolerated dose and recommended phase 2 dose(s) and evaluate the safety and tolerability, pharmacokinetics, and antineoplastic activity of escalating oral doses of TNG260 when administered with a standard dose of pembrolizumab in participants with locally advanced or metastatic STK11 mutated solid tumors.
